“These are the times that try men's souls.” | Crows and Ravens are bad for this. Very smart bird, I could go on for hours about how they key off colors of trucks of Fish & Game doing Sage Grouse studies. Go to area in nesting time, they key and find nests of grouse. Have to change and park in different spots.
Back when I worked in equipment business, I remember birds ruining silage bags picking the red spots or writing on bags. If in situations like this you need to bring AHPIS and declare war on the birds. They can take them out with poison eggs, etc. |
